I noticed the fan on my mac was spinning up even when the laptop was idle for quite a while and just doing basic tasks. So i opened up Activity Monitor and the processor had one core running at 100%. I looked for the task and it was PrintJobMgr I tried quitting the task and it worked, i thought ok maybe it was a one off. But a few hours later it was back iv quit it a few times but it just keeps stating its self again. Any ideas what it could be or how i can stop it? BTW i am running 10.5.2 and i think it has only started since i updated to .2 i attached a screen dump of Activity monitor.
